You can put this solution on YOUR website! Give two examples of theta, in radians, for which tan theta is undefined.
----------
tan = sin/cos
--> tan is undefined when the denominator = 0, ie, when cos = 0
----
That's at theta = pi/2 and theta = 3pi/2
------------
If you use a calculator to find tan(90), you get an error.
